An Easy Run That Was...Easy

The breeze was nice without being too strong on today's 4-miler, and I took it nice and easy up to Pleasant Valley Baptist Church and back. Starting yesterday afternoon I had a horrible pain in the back of my neck that went right up to the base of my skull. It bothered me all day today, but it seems as though the run helped me loosen up somewhat. Normally on Mondays I do some light barbell work that keeps the muscles in my back from barking at me, but today I skipped that part of the workout in favor of just running. Is this what getting old feels like?
